A Dell Precision 5690 that reports a full drive, runs slowly or fails to save large files has a storage problem whose cause is usually a handful of big items, and a methodical look finds them. This is a 16-inch mobile workstation, with an Intel Core Ultra processor, a professional NVIDIA RTX graphics option and a fast solid-state drive; it is used for CAD, 3D and engineering work, and those workflows produce huge files. Projects, renders, caches, simulation results and installers can fill a drive quickly, and Windows keeps its own large files too.
The checks in more detail
Start with Windows Settings, System, Storage, which shows what is using the space by category: apps, temporary files, documents and other. Turn on Storage Sense so Windows clears temporary files and the Recycle Bin on a schedule, and choose Temporary files to delete the Windows Update cleanup, thumbnails and the downloads you no longer need. A common hidden user is the Windows.old folder left by a feature update, which can take many gigabytes and is safe to remove through Temporary files when you are happy with the update.
Hibernation also stores a file the size of the memory; if you never hibernate, turning it off frees many gigabytes. Then look at your professional software. CAD and 3D programs keep caches, autosave and temporary files in the user folders and on the drive, and many have a clear-cache option. Move completed projects and archives to an external drive or a network share, and let a cloud service store files on demand rather than keeping a full copy on the laptop:
OneDrive Files On-Demand shows files without storing them. A tool such as WinDirStat or the built-in Storage settings view shows the largest folders. Do not delete system folders by hand. Keep at least 15 to 20 percent of the drive free, because a nearly full SSD slows down. If the drive is small, Dell sells larger drives, and the Precision's storage can be upgraded by a technician. Quote the service tag if you contact Dell.
